Product details
Overview
MSP430FR5858IDA from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 48KB nonvolatile memory, 2KB RAM, 12-bit ADC (14 external channels), RTC with calendar/alarm, and dual eUSCI modules supporting UART/IrDA/SPI/I²C. It operates from 1.8 V to 3.6 V and targets energy-constrained sensor nodes and data loggers.
For engineers reviewing the MSP430FR5858IDA datasheet, MSP430FR5858IDA pinout, MSP430FR5858IDA application, or MSP430FR5858IDA equivalent, key selection criteria include HFXT oscillator support (not LFXT), TSSOP-38 package footprint, 31 GPIOs with capacitive touch capability, FRAM endurance (10¹⁵ writes), and LPM3.5 current draw of 0.25 µA typical.
Technical Context
The MSP430FR5858IDA integrates a 16-bit CPUXV2 core with up to 16 MHz DCO clocking and supports high-frequency crystal (HFXT) operation only - no LFXT or RTC_B functionality per device family specification. Its memory subsystem features unified 48KB FRAM with hardware CRC and MPY32 multiplier for deterministic signal processing.
Peripherals include two eUSCI_A modules (UART/IrDA/SPI), one eUSCI_B module (I²C/SPI), five 16-bit timers (TA0–TA3, TB0), 16-channel analog comparator, and DMA controller with three channels - all optimized for autonomous low-power operation in metering and wearable applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5859IDA | 64 KB FRAM, same TSSOP-38 package, identical HFXT-only timing architecture | Higher memory headroom for complex firmware or extended data buffering | Select when >48 KB code+data space required; pin-compatible upgrade path |
| MSP430FR5848IDA | 48 KB FRAM but LFXT-only (no HFXT), lacks high-frequency crystal support | Suitable for sub-1 MHz timing-critical apps where HFXT accuracy is unnecessary | Choose only if design uses 32.768 kHz crystal exclusively; not HFXT-capable |
Compared with MSP430FR5859IDA, the MSP430FR5858IDA offers identical peripheral set and power profile but 16 KB less FRAM - ideal for cost-sensitive designs with constrained firmware size. Against MSP430FR5848IDA, it provides HFXT support essential for precise UART baud rates and high-speed sensor sampling, making it unsuitable as a drop-in replacement in LFXT-dependent systems.

FAQ
What oscillator types does the MSP430FR5858IDA support?
The MSP430FR5858IDA supports only the high-frequency crystal oscillator (HFXT) - it does not include LFXT or RTC_B functionality. External 4–24 MHz crystals must be connected to PJ.6/HFXIN and PJ.7/HFXOUT pins. This differs from MSP430FR584x variants which use LFXT only, and confirms that MSP430FR5858IDA is intended for applications requiring higher-frequency timing accuracy without 32.768 kHz real-time clock capability.
Does the MSP430FR5858IDA include hardware support for capacitive touch sensing?
Yes, the MSP430FR5858IDA supports capacitive touch sensing on all 31 GPIO pins without external components. This capability is implemented via integrated charge-transfer circuitry and software libraries (e.g., CapTIvate™), enabling robust button/slider/knob interfaces in wearables and HMI devices while reducing BOM cost and PCB complexity compared to discrete touch controllers.
What is the maximum FRAM write endurance specification for the MSP430FR5858IDA?
The MSP430FR5858IDA specifies 10¹⁵ write cycles for its 48 KB FRAM - effectively unlimited for all practical embedded applications. Unlike flash memory, FRAM performs writes at bus speed (125 ns per word) with no erase-before-write requirement, enabling reliable circular buffer logging, parameter storage, and firmware updates even during brownout conditions.
Can the MSP430FR5858IDA operate from a 1.8 V supply?
Yes, the MSP430FR5858IDA operates across a wide supply range of 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including 16 MHz DCO operation, FRAM access, and peripheral operation - subject to SVS level configuration. This enables direct integration with single-cell Li-ion or multi-cell alkaline systems without intermediate regulation.
Which communication interfaces are available on the MSP430FR5858IDA?
The MSP430FR5858IDA integrates eUSCI_A0 and eUSCI_A1 (supporting UART, IrDA, and SPI) plus eUSCI_B0 (supporting I²C and SPI). These provide flexible multi-protocol connectivity for sensor hubs, modems, and display interfaces. Notably, UART-based BSL is accessible on P2.0/P2.1, enabling in-field firmware updates without JTAG hardware.
